干支流的来水来沙受它们各自的流域特性,植被条件等因素的影响,干支流来流通常会发生不同的组合。干支流同时遭遇在水文学,涉及到防洪方面研究得要多一些,多是关注致灾性强的洪水遭遇特性如洪峰时间、洪峰量级等,而对于文章想要研究的水沙组合特性及对河床冲淤特性的影响涉及较少。文章通过长江与汉口交汇河段来探讨水沙遭遇变化对两江交汇口附近冲淤的影响。
The coming and going of dry and tributaries is affected by such factors as their own basin characteristics and vegetation conditions. Different combinations of dry and tributary currents usually occur. At the same time, dry and branch tributaries encountered more researches in hydrology and related to flood control. They paid more attention to flood-experienced characteristics such as peak hours and peak magnitudes. However, for the characteristics of water and sediment to be studied in the article and Impact on river bed scouring characteristics is less involved. The paper discusses the influence of water and sand changes on the deposition and deposition near the junction of the two rivers through the intersection of the Yangtze River and Hankou.
